When I try to upload I get a Can't Open Device: Access Denied error. If I look under Tools:Port I see multiple instances of the Uno (see attached). I've tried Remove Device from Devices and Printers, uninstall from Device Manager and everything else I can think of. Only thing that seems to work is a reboot which is a major pain as I have other things running (PVR) that I don't want to interrupt. Issue was on COM10, now has switched to COM6.
